Patent number: 6009969Abstract: A method for the automatic locking of the differentials of an all-wheel driven vehicle, slip signals being formed which, as soon as they exceed a threshold value, initiate the driving of the respective differentials. In order to take into account the influence of the steering rolling radius, the change in the steering value is ascertained. From this, using a function determined by the geometry of the vehicle, an apparent slip is ascertained. From the respective apparent slip, corrected threshold values are determined and measured slip signals are compared with the corrected threshold values and, if necessary, the driving of the respective differential is initiated. The method can also be used on a vehicle having articulated-vehicle steering.Type: GrantFiled: November 24, 1997Date of Patent: January 4, 2000Assignee: Steyr-Daimler-Puch AktiengesellschaftInventors: Harald Salcher, Gerhard Fruhwirth, Franz Stelzeneder

Patent number: 6001038Abstract: Described is a method of controlling a power distribution hydromechanical branched transmission consisting of an adjustable hydrostatic unit (4), an integrating planetary gear (10) with at least two outputs (26, 27) and, connected to the integrating planetary gear, a range-changing gear (11) designed as a double planetary gear. The two outputs (26, 27) are connected to the range-changing gear (11) by a first clutch (K1) or a second clutch (K2), and one element of the range-changing gear (11) is controlled by a third clutch (KV). Additional clutches (K3, K4) are fitted for the other ranges. In conditions in which the gear-change position is uncertain, the first clutch (K1) or the second clutch (K2), depending on the instantaneous speed of the vehicle, is synchronized and engaged by adjusting the hydrostatic unit (4), and then either one of the other clutches (K3, K4) or the third clutch (KV) is synchronized and engaged.Type: GrantFiled: June 25, 1998Date of Patent: December 14, 1999Assignee: Steyr-Daimler-Puch AktiengesellschaftInventors: Gebhard Wontner, Josef Leitner

Patent number: 5980411Abstract: A method of changing the range of a hydrostatic/mechanical power split transmission is specified: firstly, the command to engage the clutch for the next range is given, then the transfer of the load to this clutch is carried out and then the command to disengage the clutch for the old range (V.sub.x) is given if, during the load transfer, a characteristic speed value of the summing planetary gearbox (10), for example the speed of the planet carrier (25), remains constant. In this way, the sensors for the clutches are dispensed with and quicker changes of range are made possible.Type: GrantFiled: October 29, 1998Date of Patent: November 9, 1999Assignee: Steyr-Daimler-Puch AktiengesellschaftInventor: Gebhard Wontner
